Max V, dual speed grade compile - Max V, dual speed grade compile I get a different program file when I compile with the 5M80ZT100C4 and the slower C5 device. Both speed grades pass timing. I would like to be able to use either device in manufacturing with the same program file. Is this possible? What do I need to do? Replies: Re: Max V, dual speed grade compile Hi Bryan, May i know what do you mean by programming files are different? The size of the SOF generated? Best regards, Bruce Replies: Re: Max V, dual speed grade compile Thanks for the reply. I am still curios why it is stated that it is speed grade independent when the program files are different when recompiled with the "4" and "5" speed grades. I'm just going to use the slower, 5, grade and move on. Best regards, Bryan Replies: Re: Max V, dual speed grade compile Yes, it is possible. Programming files are speed grade and temperate grade dependent. https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/solutions/rd02072008_497.html
